MACHBLOC™ HVOF masking compound was developed to withstand the rigors of the HVOF plasma spray environment. MACHBLOC™, in the uncured state, is a soft, conformable putty-like material. MACHBLOC™ is great for masking holes, grooves, key slots or any unique configuration for both plasma spray and HVOF processes. Once cured MACHBLOC™ becomes a strong, abrasion-resistant mask allowing users to take full advantage of HVOF coating technology.
